R-Scan Array Setup and Operation

Manual mode

To prepare and connect the system together for a manual inspection:
1. Power on the PA UT instrument
2. Connect the probe cable and encoder cable to the instrument.
3. For a manual mode inspection ensure the high friction wheels are in place on the scanner.
4. Insert the probe into the water box by:
a. Unscrewing and remove the 4 cap head bolts and washers using a 3mm hex key.
b. Removing the supplied probe seal (page 17, item 21 of figure 7) from the water box and
fixing to the probe.
c. Sliding the probe into the top of the water box.
d. Replacing the 4 cap head bolts and washers, using a 3mm hex key, to secure the probe.
CAUTION
To ensure a watertight seal between probe and water box, check the probe sits flush with the
top of the water box and the sealed gasket is fitted.
5. Select the required water box wedge required for the application. Use the four captive thumb
screws the remove and fit the wedge to the water box.
NOTE
It is recommended to use the 15mm wedge if the thickness of test item is 25mm or less and
use the 30mm wedge if the thickness is greater than 25mm.
CAUTION
To ensure a watertight seal between water box and water box wedge, check the probe sits
flush with the top of the water box and the sealed gasket is fitted.
6. Open the pressure release valves on the water box, if not already open.
7. On the scanner disengage both probe lock levers by pushing each lever down.
8. Insert the water box with fitted probe into the scanner chassis from the top and push down.
IMPORTANT
Ensure element 1 of the probe is positioned on the left-hand side of the scanner when looking
forward. Element 64 is located next to the probe lock on the right-hand side of the scanner.
9. Secure the water box in the chassis by lifting both probe lock levers up to clamp in position.
NOTE
The water box height will need to be adjusted once on the test item.
10. If the probe cable is not already housed in the spiral wrap umbilical, insert it into the spiral wrap
by using the spiral wrap tool suppled.
CAUTION
Ensure that no undue strain can be put on the probe cables.
